The pathological changes in vaccinated IL-10KO and WT mice following intranasally (i.n.) challenge infection after BCG vaccination. Pretreated mice were challenged intranasally with CFUs BCG and analyzed for histopathological changes in the lungs at day 21 postchallenge infection. Lung tissue sections (6 μm) were stained with H&E for inflammation. (a) Low magnification (×10), (b) High magnification (×40). The representative of three independent experiments () with similar results was shown.
